I am reading the Oreilly book "Programming ColdFusion MX 6.2" by Rob
Brooks-Bilson. I have been programming CF for a few years, but I am new to the
Remoting Model. I updated my Flash 2004, and I am having trouble following the
examples in the book. My UI components don't operate in the same manor as the
ones in the book. THey even look different. For example, I am creating two
dynamic drop down boxes, when you select a name in the first box, it populates
the second box. Then you click on a pushbutton to retrieve all the user
information. Here is the code.

#include "NetServices.as"
#include "DataGlue.as"
#include "NetDebug.as"

// --------------------------------------------------
// Application initialization
// --------------------------------------------------
if (inited == null) {
// do this code only once
var inited = true;

// set the default gateway URL (this is used only in authoring)
NetServices.setDefaultGatewayUrl("http://localhost/flashservices/gateway");

// connect to the gateway
var gateway_conn = NetServices.createGatewayConnection();

// get a reference to a service
var myService = gateway_conn.getService("programmingcf.ch28.employee", this);
}

// --------------------------------------------------
// cb1 combo box
// --------------------------------------------------
//call the getDepartments() method
myService.getDepartments();

//Bind the results to the cb1 combo box using data glue
function getDepartments_Result (result) {
DataGlue.bindFormatStrings(cb1, result, "#Department#", "#Department#");
}

// --------------------------------------------------
// cb2 combo box
// --------------------------------------------------
// When a selection in the first combo box is made, call showEmployees()
cb1.setChangeHandler("showEmployees");

function showEmployees(component){
cb2.removeAll( );
myService.getEmployees(cb1.getSelectedItem( ).data);
cb2.addItem("loading...","");
}

function getEmployees_Result(result) {
cb2.removeAll();
for (var i = 0;i < result.items.length;i++) {
cb2.addItem(result.items.Name,result.items.ID);
}
}

// --------------------------------------------------
// Button handler and full record get/display
// --------------------------------------------------
// Retrieve the full employee record based on the employee selected
function employeeHandler(){
myService.getEmployee(cb2.getSelectedItem( ).data);
}

// Display the full employee record
function getEmployee_Result(result) {
dName.text = result.items[0].Name;
dTitle.text = result.items[0].Title;
dDepartment.text = result.items[0].Department;
dEmail.text = result.items[0].Email;
dPhoneExt.text = result.items[0].phoneExt;
}
stop();

This works great if I use the example provided with the book (the code
downloaded from oreilly's website). But the drop down box looks different than
the one I have. I have two lists in the Components window "Flash UI Components
Set 2" and "UI Components". I am pulling them from the "UI Components" section.

Something I have noticed is that in my combo boxes, I can change the options
in the Component Inspector, but not in theirs. It is as if they are using an
older version of the boxes. That's fine, but how do I get the data to work with
mine? When I run the .swf file in Flash, they are blank, I don't even get the
drop down arrow. Clearly it is not bound to something it needs to be, right?

As always, thank you for educating me!

Hey Pauly,
With the release of FMX2004 Macromedia released a completely revised set
of components that use ActionScript 2.0 (rather than ActionScript 1.0).

They new components do look (and behave) lightly differently than the
older ones (in FMX).

You can still use V1 components in FMX04 but Macromedia recommends
against this. The reason being that that V1 components haven't been
optimised to run under FMX04 and as such can produce unpredictable
results/errors. They may work fine...but then again they might not.

I suggest you just stick with the V2 components in FMX04 and you should
be ok.
